Dahua DH-IPC-HFW2439SP-SA-LED-0280B-S2 4MP Full Color Surveillance Camera – IP67, PoE, Warm LED Light

The Dahua DH-IPC-HFW2439SP-SA-LED-0280B-S2 is an outdoor bullet IP camera with Full-color Starlight technology, designed for residential and commercial surveillance systems where continuous color recording at night without additional artificial lighting is the primary requirement over conventional IR cameras that produce monochrome nighttime images. Part of the Dahua WizSense series, it is commonly deployed for monitoring entrances, parking areas, and perimeters where color identification of clothing, vehicles, and objects in low-light conditions adds operational value compared to black-and-white IR imaging.

The 4MP sensor with a fixed 2.8mm wide-angle lens captures images at 2560×1440 resolution with dual illumination — white LEDs for color imaging and IR for zero-light conditions — selected automatically based on ambient lighting. H.265+ compression reduces storage and bandwidth consumption by up to 50% compared to H.264 at equivalent video quality, relevant for systems with continuous 24/7 recording over extended periods. SMD (Smart Motion Detection) filters false alarms triggered by vegetation movement or animals, generating alerts only for human or vehicle presence.

The camera is powered via PoE (IEEE 802.3af) over a single network cable, eliminating separate power cabling and simplifying installation in locations without nearby power outlets. IP67 protection ensures reliable operation in rain, dust, and temperature variations typical of permanent outdoor installations. The built-in audio input supports connection of an external microphone for synchronized audio and video recording, useful in applications where audio evidence complements video footage.

Recommended for installers and integrators equipping residential building perimeters, parking areas, commercial entrances, and industrial zones with 4MP Full-color PoE bullet IP cameras where nighttime color imaging, SMD detection for false alarm reduction, and H.265+ compression for storage optimization are the defining requirements of the surveillance system.
